GRILLE Filed April 19, 1944 Patented Mar. 19, 1946 means GRILLE Robert L. Leigh, Grand Rapids, Mich, assignor to Air Control Products, Inc., Coopersville, Mich, a corporation of Michigan Application April 19, 1944, Serial No. 531,821

2 Claims.

The prevent invention relates to grilles and more particularly to air grilles.

The primary objects of the instant invention are to provide a grille of the general character above indicated whose several transverse members may be readily and conveniently assembled; to provide such a grille whose several transverse members, when in their assembled relation, remain in a plane after installation and do not thereafter become distorted; to provide such a grille whose several transverse members, irrespective of thickness of stock, do not militate against or increase difiiculties of assembly; to provide such a grille which is rigid and whose several transverse members are firmly interlocked after assembly and remain so after installation; and, to provide such a grille which is pleasing in appearance, efiicient in use, and reasonably economical in manufacture and assembly.

An illustrative embodiment of the invention is shown in the accompanying drawin wherein:

Figure l is a fragmentary perspective view of the grille and its frame member;

Figure 2 is a side elevational view of one of the several members of the grille proper, brokenaway to indicate potential differences in length of a given member;

Figure 3 is a side elevational view of one of the several transverse members of the grille itself, broken away to likewise indicate potential dilTerences in length of any given member;

Figure 4 is a fragmentary side elevational view of one of the grille members showing in full lines an end elevational view of a transverse grille member in cross section prior to its interlocking relationship with the first member and showing in dotted lines its interlocked relationship;

Figure 5 is a view similar to Figure 4 but showing a pair of the transverse members secured in interlocked relationship; and

Figure 6 is a fragmentary view showing the manner in which all of the several transverse members are secured to their oppositely disposed frame members.

Referring then to the drawing wherein like parts of the structure shown are designated by the same numerals in the several views, a grille primarily though not specifically intended for use as a floor face air grille, comprises a plurality of spaced apart vertically disposed elongated slat members ll), preferably of stamped sheet metal, each provided with a plurality of equally spaced slots H along one edge thereof and below each of which slots is an aperture l2, the opposite ends of each of which members is provided with a hook l3.

A plurality of spaced apart vertically disposed elongated slat members it, likewise preferably of stamped sheet metal, are transversely disposed relatively to the members ID when in assembled relation, said members 14 each having at its lower edge a plurality of equally spaced substantially in clined slots l5, each slot having an inclined wall and a vertical wall and provided at the lower end of the vertical wall with a laterally disposed lug it and each of which members is provided with a hook I! on each of its opposite ends of the character of the hooks 13 on the opposite ends of the members ID.

A rectangular frame for the assembled grille comprises a pair of oppositely disposed and spaced apart angle members l8, l9, also preferably of stamped sheet metal, each oppositely disposed angle member having a series of spaced apertures 20 adapted to register with the hooks I3, I! of the members Ill, M respectively when in their assembled relation.

In assembling the grille of the present invention, the several members it are fixedly secured to the several members i l in parallel spaced apart transverse interlocking relationship by inserting a slot 15 of a member it within a slot ll of a member I0 and then rotating the member ID toward the member Hi from its position shown in full lines in Figure 4 to its position shown in dotted lines in the same view or to its position shown in Figure 5, the lug it of the member I4 enterin the aperture of the member it.

After such assembly of the grille member it, M as above described, the hooks Id at each end of a given member it are seated within the apertures 20 of the spaced oppositely disposed angle members l8 and the hooks ii at each end of a given member Hi are seated within the apertures 20 of the spaced oppositely disposed members l9, after which the rectangular frame I8, i9 is secured together in any suitable fashion as by spot welding if the frame is of stamped sheet metal.

It will thus be seen that the grille herein shown and described is pleasing in appearance, efficient in use and reasonably economical in manufacture and while but one specific embodiment of the invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted with out departing from the spirit of the invention as the same is defined by the following claims.

I claim:

1. A grille of the class described including a frame comprising a pair of spaced apart frame. I

members, each having an oppositely disposed aperture; and a second pair of transversely positioned spaced apart frame members, each having an oppositely disposed aperture; a slat member provided with hooks at its opposite ends and having a transverse slot along One edge thereof and 'an aperture therebelow; and a second slat member provided with hooks at its opposite ends and having a slot along one edge thereof with an inclined wall and a vertical wall, the open end of the slot of said second slat member having a laterally projecting lug, said second slat member being disposed transversely of the first slatmember and seated in the slot of thefirstmember and its lu interlocked within the aperture of the first member, the hooks of each slat member beingseated within oppositely disposed apertures of a pair of spaced apart frame members.
